n INDEX TAB.

tab which .may be quickly and easily at-.

tached to various objects; which will not ."pull loose from the object to which it is attached, which protects the index slip against soiling by handling; with which the index information maybe changed at will; in which the component parts will not oosenfrom one another in use; which may beattached to the object so as to. project from the edge thereo'for fit closely to the edge; which may be readily divided by the any desired purchaser into tab units of durable, attrac- Other lengths, and which is simple, 'tive in appearance, and inexpensive. objects and advantages will be apparent from the following description of an embodiment of the invention and the novel features will be particularly pointed out in claims.

In the embodiment illustrated, particularly in Figs. 1 to 9, a doubled strip 1 of sheet transparent material is provided along the edge portion of each arm with a row of apertures 52. llhe transparent material may be formed from relatively thin sheet celluloid or from other substances having similar physical characteristics, and may be clear or may be of any desired colors. Strips of flexible material such as thin tough paper,

fabric, or other similar materials are doubled lengthwise of themselves to form attaching members 3. The abutting faces of the arms of the doubled attaching members are each gummed or otherwise provided with an adhesive coating 4. A doubled attaching member 3 is placed over the longitudinal edge of each arm of the strip with the arms of the member embracing the arm of the strip. The gum or adhesive coatin d is effective to cement the attaching mem ers to the embraced arms of the strip and by pressure the members may be and preferably are forced into the apertures of the strip and through the apertures cemented directly to one another so as; to be mechanically i nterlocked through the apertures to the strip, as shown clearly in Fig. 4:.

Because. of the connection between the arms or each attaching member 3 at its folded edge that lies along the embraced edge of the strip 1, each arm of the member will resist the loosening of the other arm from-the strip, and consequently the attaching members will he more firmly attached to the strip than if single strips were cemented merely along the inner faces of the arms of the strips.- This constitutes in edect an interloching arrangement between the embracing arms f each attaching member.

The surfaces of the applied members which face one another between the arms of the strip arealso gummed or provided with a suitable adhesive coating 5, by which the tab may be cemented toan edge portion of a thin object such as an index card or book sheet 6. The tab may be applied to an ohyect or card so as to project from the edge Iltlll projecting doubled portion of the transparent strip formswith the edge of the object an open ended pocket for removably receiving an index slip or label 7 or 7 upon which suitable information or index data has been placed. This information or data is easil visible through the transparent strip. The slip may be straight as designated by the reference 7 or-doubled lengthwise, as designated by reference 7, and may have suitable information or data upon one or both faces so as to be visible through the transparent strip from eitheror both faces of the object. The tab may, if desired, be applied closely to the edge of the object or card 6, as shown in Figs. 6 and 7, in which case the index slip is inserted endwise between the unattached portion of the strip and the .card. The celluloid or transparent strip may be roughened, such as by fine sand paper, along the portions engaged by the adhesive so as to insure firm adherence thereto of the attaching members.

In the embodiment illustrated in Figs. 10

to 12, a thinsheet 8 of transparent material is doubled lengthwise to form the protecting ,strip. A sheet 9 of tough thin paper or fabric is doubled lengthwise upon itself and telescoped within the transparent strip with the arms of the sheet 9 which forms the attaching member, of greater length than the arms of the transparent strip. The arms of the strip 8 are provided with integral tongues 10 extending from the edges, and the tongues are inserted through apertures in the attaching member or sheet 9 and then folded along the face of the sheet 9 so as to mechanically interlqck the strip 8 to the attaching sheet or member 9. The tongues upon opposite arms of the transparent strip are staggered with respect to one another so as to pass one "another when the sides of the tab are pressed together. The inner face of the doubled sheet 9 is gummed or otherwise provided with a suitable adhesive coating 11 by Which the tab may be applied to an object, such as a sheet, or card In applymg this tab to an object, the adhesive coating is moistened or otherwise" rendered active and the tab is then applied over the edgeof the object, after which the arms of "the tab are pressed firmly against the opposite faces of the object until the adhesive sets.v The index slip or label 7 or 7 which has been provided with the desired information or indexing data may .then' beinsertedf endwlse into the open ended pocket formed .alongthe doubled edge between the telescoping strip and sheet.

The information or data upon the index slip will-be readily "visible through the transparent strip, and this data may be proylded upon both arms of the index slip, if a; folded slip 7 is used, so as to be visible Figs. 10 and 12 the tongues 10 will be cemented by the adhesive coating 11 to one or both arms of the attaching sheet or member 9 as well as interlocked-therewith so that there is little or no possibility of the tongue being disengaged from the sheet 9 in use.

In both of the illustrated embodiments, the tab may be quickly, easily, effectively and securely attached to various objects, and the component parts, will not become disengaged from one another in use. The index slips or labels will be protected from soiling and wear in handling. The tabs and index slips may be marketed in strips of any suitable length and divided into the desired lengths by the purchaser by merely cutting the same between apertures or tongues with a knife or shears. The index tabs of various colors further indexing combinations are possible.

It will be obvious that various changes in the details and arrangements of parts of the embodiments herein described and illustrated for the purpose of explaining the nature of the invention may be made by those skilled in the art within the principle and scope of the invention;

3. In an index tab, a doubled strip of transparent material, flexible attaching members interlocked with the edge portions of the arms of the strip, by which the strip may be secured to an edge ofa thin ebject,

thedoubled portion of the strip serving asan open ended pocket to receive and retain an. index slip. 4. Inan index tab, a doubled strip of transparent material, havin a row of apertures along the opposite e lge portions of each arm, and a doubled flexible attaching member embracin each edge of the strip, the embracing su ace ofeach member having an adhesive coating which cements the member to the strip and the opposite arms of the member directly together through the apertures, the doubled portion of the strip serving as an open ended pocket to receive and retain an index slip when the strip is attached by said member to a thin object.

5. In anrindex tab, a unit comprising a doubled strip of transparent material having an aperture in each arm, a flexible attaching member embracing the edge portion of each arm of the strip, the embracing portions of each member being cemented to the embraced arm of the strip and also cemented directly to one another through the aperture, the doubled portion of the strip serving as an open ended pocket to receive and retain an index slip when the strip is attached by said members to an object.
